One important thing to realize or notice when it comes to Korean dramas or any other Asian drama is that a lot of them are based on manga/manhwa which are comparable to a comic. Many of my most favorite dramas are based on these manga and I find this very exciting because it is like your favorite book being published. This is also the reason that I enjoy anime as well because a lot of the times the manga turned into a drama has also been turned into a anime. manga are made in Japan and manhwas are made in Korea but a lot of Korean dramas are made from manga. Some dramas that are from manga is
Boys Over Flowers: This manga was used a lot I am pretty sure it has been turned into an anime and has been made into a Japanese and Korean drama. It did extremely well as a Korean drama.
Mary Stayed Out All Night: This is made from a manhwa and was turned into a Korean drama
Playful Kiss: this manga was turned into a Taiwanese drama, Korean Drama and a Japanese Drama.
Skip Beat: This is one of my most favorite mangas!! it has been turned into an anime and recently was turned into a Taiwanese drama but they had Kpop Super Junior Siwon and Donghae play some of the main characters!! I have heard some rumors that there is going to be a Korean drama of Skip-beat which makes me very happy!!
Absolute Boyfriend: is a manga that has been turned into a Japanese Drama, and a Taiwanese Drama. There has been reports that there could be a Korean adaptation.
Fated to Love You: is a little different it started as a drama and then was turned into a manhua but I found it first as a manhua and then found the drama.
Full House: is a manhwa turned into a Korean drama.
To The Beautiful You: is a manga that has been turned into a Taiwanese drama, Japanese drama twice and recently a Korean drama.
Goong: is a manhwa turned into a Korean drama.
I am sure there are a lot more manga based dramas and I know that this will continue! I think it is the best thing to read a manga and then find out there is a drama based on it!! or that soon there will be!! its as exciting as Christmas!!
